下文主要講述如何利用python自帶的庫模擬http請求，為以后利用python做API測試做准備。
只講述模擬http的過程，具體到自己用的時候，要以自己的應用為准做出適當的調整。
#!coding:utf-8 相信這句大家都懂的，不解釋 #導入需要的python模塊httplib，用來模擬提交http請求，詳細的用法可見python幫助手冊 import httplib #導入需要的python模塊urllib，用來對數據進行編碼 import urllib #定義請求頭 reqheaders={'Content-type':'application/x-www-form-urlencoded', 'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'Host':'www.renren.com', 'Origin':'http://zhichang.renren.com', 'Referer':'http://zhichang.renren.com', 'User-Agent':'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1',} #定義post的參數 reqdata={'email':'xxxx@xxx.com', 'password':'xxxx', 'autoLogin':'on', 'origURL':'http://zhichang.renren.com/?login_state=rr', 'domain':'renren.com' } #對請求參數進行編碼 data=urllib.urlencode(reqdata) #利用httplib庫模擬接口請求 #先連接到人人 conn=httplib.HTTPConnection('renren.com') #提交登錄的post請求 conn.request('POST', '/PLogin.do', data, reqheaders) #獲取服務器的返回 res=conn.getresponse() #打印服務器返回的狀態 print(res.status) #以dictionary形式答應服務器返回的 response header print(res.msg) #打印服務器返回請求頭中設置的cookie print(res.getheader('Set-Cookie')) #以下為運行程序后的結果 302 登錄成功后重定向了 Server: nginx/1.2.0 Date: Sat, 15 Feb 2014 04:47:09 GMT Content-Length: 80 Connection: keep-alive Cache-Control: no-cache Pragma: no-cache Expires: Thu, 01 Jan 1970 00:00:00 GMT Location: http://zhichang.renren.com/?login_state=rr 重定向的URL Set-Cookie: anonymid=hroelq3l-czxmdy; domain=.renren.com; path=/; expires=Thu, 14-Feb-2019 04:47:09 GMT Set-Cookie: _de=97FB170A42B4342D1C47A157AD77AAFC1383380866D39FF5; domain=.renren.com; path=/; expires=Tue, 10-Feb-2015 04:47:09 GMT Set-Cookie: p=31991a0a194c34e606ef1263317b06372; domain=renren.com; path=/; expires=Mon, 17-Mar-2014 04:47:09 GMT Set-Cookie: ap=229996362; domain=renren.com; path=/; expires=Mon, 17-Mar-2014 04:47:09 GMT Set-Cookie: first_login_flag=1; domain=renren.com; path=/ Set-Cookie: t=c5424876f4a3363b98b6f92e677f04bc2; domain=.renren.com; path=/ Set-Cookie: t=a0196d1d663ad5a060ee47466123042d; domain=renren.com; path=/xtalk/ Set-Cookie: societyguester=c5424876f4a3363b98b6f92e677f04bc2; domain=.renren.com; path=/ Set-Cookie: id=229996362; domain=.renren.com; path=/ （這個是返回的人人ID） Set-Cookie: xnsid=cc216a6b; domain=.renren.com; path=/ （有這個就登錄成功了） Set-Cookie: loginfrom=syshome; domain=.renren.com; path=/ #以下就是cookie了，以后發請求，就可以帶上這個cookie anonymid=hroelq3l-czxmdy; domain=.renren.com; path=/; expires=Thu, 14-Feb-2019 04:47:09 GMT, _de=97FB170A42B4342D1C47A157AD77AAFC1383380866D39FF5; domain=.renren.com; path=/; expires=Tue, 10-Feb-2015 04:47:09 GMT, p=31991a0a194c34e606ef1263317b06372; domain=renren.com; path=/; expires=Mon, 17-Mar-2014 04:47:09 GMT, ap=229996362; domain=renren.com; path=/; expires=Mon, 17-Mar-2014 04:47:09 GMT, first_login_flag=1; domain=renren.com; path=/, t=c5424876f4a3363b98b6f92e677f04bc2; domain=.renren.com; path=/, t=a0196d1d663ad5a060ee47466123042d; domain=renren.com; path=/xtalk/, societyguester=c5424876f4a3363b98b6f92e677f04bc2; domain=.renren.com; path=/, id=229996362; domain=.renren.com; path=/, xnsid=cc216a6b; domain=.renren.com; path=/, loginfrom=syshome; domain=.renren.com; path=/
